heater core

I need to replace the heater core in my 01 sahara. How much of a pain will this be? Any tips/tricks or things I should watch out for? I have replaced heater cores in the past, but they have primarily been on older Ford pickups, and they are pretty easy...

I'd remove the passenger seat first, that will give you more room to move/sit/look and work.

Once you find the three nuts that hold the assembly on the firewall, it's pretty easy to pull out. One is right behind the cyl head - other two are identical in size and shape and will be on either side about 12" away.

Get the seal you need, foam about 3" thick, before you start taking it out.

Drain out most of the fluid from the radiator, but expect to get some spilled when you pull the old core out.

When you have it out, clean it up, paint it generously and re-seal the halves of the assembly with RTV - make sure that the hose that goes through the firewall and dumps water, coolant, yuk is intact, not clogged and doing it's job. If it's trashed make a new one with some tubing and a right angle connector.

That's everything that I can think of

have fun!

Dyna said just remove the battery and unscrew few things and the heater core will come out from engine side, not under the dash. There are 3 screws holding it in. Search for the posts by Dyna.
